Do you have any performance issues? such as long STW GC pauses or high
p99.9 latency? If not, then you shouldn't tune the GC for the sake of
it. However, if you do have performance issues related to GC, regardless
what is the GC metric you are looking at saying, you will need to
address the issue and that probably will involve some GC tunings.

Hi,
We are using Apache Cassandra 3.11.2 with its default gc configuration
(CMS and ...) on a 16GB heap, i inspected gc logs using gcviewer and
it reported 92% of throughput, is that means not necessary to do any
further tuning for gc? and everything is ok with gc of Cassandra?
